Da dove si comincia con git? Quali sono i concetti di base per iniziare? In questo video imparerai:
Come ci si può ricordare tutto quello che ogni giorno dobbiamo fare? R.A.D.E. è l’acronimo che raccoglie il metodo che uso da anni con successo: raccogliere, analizzare, decidere, eseguire. In questo video spiego passo-passo in cosa consiste.
“Non ho tempo” “Comincio la settimana prossima” “Ho altre cose più urgenti da fare” Tutti abbiamo detto a noi stessi qualcosa di simile quando si tratta di fare qualcosa di nuovo, diverso o fuori dalla propria zona di comfort. Però il momento migliore per agire è ADESSO e in questo video dico la mia sull’argomento 😄
Esploriamo insieme tre concetti sulla produttività che sono poco noti. Un confronto tra termini simili e due principi dai nomi altisonanti.
È inutile che mi viene a dire che sai fare più cose contemporaneamente.
Il multitasking non esiste!
The last generations of gaming consoles are great. Super powerful, always connected, 4K-60FPS-HDR10-Blablabla. I believe, however, that the overall experience of gaming is not directly related to the power of the gaming engine or hardware.
My first memories of videogames goes back to mid 90s. Super Nintendo (SNES) was the first console I remember with some of the most innovative games: Super Mario World, Zelda: A Link to the Past, Street Figher II: The World Warriors, Mortal Kombat, Kirby…
I’ve got vivid memories of the time spent with friends racing with Super Mario Kart on a split screen, fighting versus my brother or the CPU at Street Fighter II (SNES).
So, for Christmas vacation, I resurrected a forgotten Raspberry 3. I googled “raspberry retrogaming” and I found the RetroPie project.
RetroPie allows you to turn your Raspberry Pi, ODroid C1/C2, or PC into a retro-gaming machine. It builds upon Raspbian, EmulationStation, RetroArch and many other projects to enable you to play your favourite Arcade, home-console, and classic PC games with the minimum set-up.

When they say minimal setup, it’s true. This is mine:
When the setup was complete (about 30 minutes to 1 hour) I showed Super Mario World to my two kids (4 and 6 years old). The moment the soundtrack started playing I was teleported back to when I was 6 years old. I told the story of Mario, Princess Peach and Bowser to them and started exploring the world. They didn’t care about the low quality of the graphics and the flat music, we laughed together when I fell from the screen, and we celebrated when we defeated the Koopas inside the castles. I hope they will remember these moment together as I do.
The Azure Pipelines is the feature of Azure DevOps that allows you to automate your build and release processes, to unleash the full potential of CI/CD practices.
Pipelines can be simple or complicated but, it’s very likely that you need to specify some kind of input to a Pipeline just before starting it.
This is where variables come to help when you’re using the classic version of Azure Pipelines. Inside the Variable tab you write variables and then you can set if it’s “settable at queue time”. This way, when you start the pipeline, a slice of UI will provide a prompt to complete. The input is treated as a string and you can’t do much more.
If you’re trying to achieve the same thing with YAML pipelines you can rely on the power of parameters. Actually, you can achieve more with YAML pipelines!
Runtime parameters let you have more control over what values can be passed to a pipeline. With runtime parameters you can:
https://docs.microsoft.com/en-us/azure/devops/pipelines/process/runtime-parameters
– Supply different values to scripts and tasks at runtime
– Control parameter types, ranges allowed, and defaults
– Dynamically select jobs and stages with template expressions
Because parameters are explicitly typed you can create a better user experience for users of your pipelines with a fully featured UI with check-boxes, radio-buttons and text areas. You can do this in 3 easy steps. Open your YAML definition and for each one of the inputs that you need:
This an example of a YAML Pipeline definition that accepts a string as an input to complete the famous “Hello World” greeting but, within a set of specific allowed values. Also, the default value is set to world.
parameters:
- name: myString
displayName: string
type: string
default: 'world'
values:
- world
- mondo
pool:
vmImage: 'ubuntu-latest'
steps:
- script: echo Hello, ${{ parameters.myString }}!
displayName: 'Run a one-line script'
When you Run the pipeline the UI shows specific fields to collect your input (greetings in our example).
I suggest you to try with all the parameters type that the YAML schema provides. This is a complete example showing all the available options:
parameters:
- name: myParameter
displayName: greetings
type: string
default: 'world'
values:
- world
- mondo
- name: myNumber
displayName: 'Number'
type: number
default: '1'
values:
- 1
- 2
- 3
- name: myBoolean
type: boolean
default: true
- name: myObject
type: object
default:
foo: FOO
bar: BAR
things:
- one
- two
- three
nested:
one: apple
two: pear
count: 3
- name: myStep
type: step
default:
script: echo my step
- name: mySteplist
type: stepList
default:
- script: echo step one
- script: echo step two
pool:
vmImage: 'ubuntu-latest'
steps:
- script: echo Hello, ${{ parameters.myParameter }}!
displayName: 'Run a one-line script'
The resulting UI is:
Isn’t this awesome?
Thanks to my friend Giulio Vian of getlatestversion.it for the heads-up about this feature. The official Microsoft doc lacks a detailed explanation of this specific usage of YAML Pipelines parameters!
Every IT professional / programmer / developer has a toolkit to do be more productive. It’s the based on years of experience, tips from colleagues, friends, and experts.
This is my list of tools that I use more often. I don’t use every tool every day.
This is my first list and it will be interesting to see how this will evolve year over year.
Misc
Windows Terminal / If you are a terminal user this is for you. It’s a modern implementation of a terminal for Windows. Its main features include multiple tabs, panes, Unicode and UTF-8 character support, a GPU accelerated text rendering engine, and the ability to create your own themes and customize text, colors, backgrounds, and shortcuts.
Chocolatey / The Package Manager for Windows. Forget browsing to the website of your favorite tool, click download, open the setup, next-next-next-finish. Just write choco install mytool -y and you’re done!

La configurazione delle applicazioni è, di norma, gestita con dei file di configurazione che i programmi leggono in fase di boot o runtime.
Come si gestisce questo tipico scenario in ambito Kubernetes? In questo video spiego brevemente cosa sono le ConfigMap e come utilizzarle con un piccolo esempio.
In questo esempio la ConfigMap con nome myconfigini è creata a partire da un file di testo con lo switch –from-file.
kubectl create configmap myconfigini --from-file=.\tmweb\config\MyIniConfig.ini
Qui di seguito riporto il manifest YAML con il deployment con ConfigMap mostrato nel video. La configMap viene usata facendo il mount di un volume. Tale volume viene definito nella sezione spec del template e referenziato nella sezione container colla sintassi volumeMount.

I was preparing a demo about IIS XML Transformation inside a CD pipeline with Azure DevOps.
It’s very likely that if you’re working with an ASP.Net project with default values the Azure App Service Deploy Task will fail. After some googling I found that this is documented here.
The trick is to remove the <DependendUpon> tag inside the csproj file.
By default, MSBuild applies the transformation as it generates the web package if the
File transforms and variable substitution reference, XML transformation notes, Microsoft Docs<DependentUpon>element is already present in the transform file in the*.csprojfile. In such cases, the Azure App Service Deploy task will fail because there is no further transformation applied on theWeb.configfile. Therefore, it is recommended that the<DependentUpon>element is removed from all the transform files to disable any build-time configuration when using XML transformation.
